The global temperature rose by 0.2�C between the middle 1960's and 1980, yielding a warming of 0.4�C in the past century. This temperature increase is consistent with the calculated greenhouse effect due to measured increases of atmospheric carbon dioxide. Variations of volcanic aerosols and possibly solar luminosity appear to be primary causes of observed fluctuations about the mean trend of increasing temperature. It is shown that the anthropogenic carbon dioxide warming should emerge from…

Present estimates are that limiting the increase in global average surface temperature to no more than 2–2.5 °C above its 1750 value of approximately 15 °C will be required to avoid the most catastrophic, but certainly not all, consequences of climate change.


The presence of radiatively active gases in the Earth's atmosphere (water vapor, carbon dioxide, and ozone) raises its global mean surface temperature by 30 K, making our planet habitable by life as

Recent temperature changes in the Arctic and Antarctic

The possibility of a global warming induced by increasing levels of atmospheric carbon dioxide has led to increased interest in monitoring global temperatures. Polar regions are of particular

Arctic carbon sinks: Present and future

Surface air temperatures of the Arctic rose 1.2° −1.5°C from 1880 to 1980, in contrast to a global warming of only 0.4° −0.5°C; since 1980, six of the warmest years in the past century have been

Climate Change in Western North America caused by CO2 rise: A Coupled Atmosphere-Ocean Model Simulation

This study investigates the interactions between carbon dioxide, global atmospheric circulation and the climate of the cordillera of western North America in the twenty-first century under a

Differences in the efficacy of climate forcings explained by variations in atmospheric boundary layer depth

It is shown that the efficacy of a forcing is determined by the effective heat capacity of the atmosphere, which in cold and dry climates is defined by the depth of the planetary boundary layer, which can vary by an order of magnitude on different temporal and spatial scales.

Through the use of fossil fuels as an energy source, mankind is slowly changing the constitution of the atmosphere. The emission of CO2 and other greenhouse gases changes the radiative properties of


The paper reviews the climatic changes that took place during the Quaternary, in particular those of the Holocene, including the historical time. The role of carbon dioxide, as a greenhouse gas, is



Detecting Climate Change due to Increasing Carbon Dioxide

The results indicate that the surface warming due to increased carbon dioxide which is predicted by three-dimensional climate models should be detectable now is not, possibly because the predicted warming is being delayed more than a decade by ocean thermal inertia, or because there is a compensating cooling due to other factors.

Climatic Change: Are We on the Brink of a Pronounced Global Warming?

If man-made dust is unimportant as a major cause of climatic change, then a strong case can be made that the present cooling trend will, within a decade or so, give way to a pronounced warming

Arctic sea ice decay simulated for a CO2-induced temperature rise

A large scale numerical time-dependent model of sea ice that takes into account the heat fluxes in and out of the ice, the seasonal occurrence of snow, and ice motions has been used in an experiment

The Climatological Significance of a Doubling of Earth's Atmospheric Carbon Dioxide Concentration

There appears to be a major discrepancy between current theory and experiment relative to the effects of carbon dioxide on climate, which should not be too quick to limit the options in the selection of future energy alternatives.

An empirical determination of the heating of the Earth by the carbon dioxide greenhouse effect

Numerous theoretical calculations1,2 have been made of the effect of an increased carbon dioxide concentration in the atmosphere on the surface temperature of the Earth. Estimates of the increase in

Greenhouse Effects due to Man-Made Perturbations of Trace Gases

A one-dimensional radiative-convective model for the atmospheric thermal structure is used to compute the change in the surface temperature of the earth for large assumed increases in the trace gas concentrations; doubling the N2O, CH4, and NH3 concentrations is found to cause additive increases inthe surface temperature.

West Antarctic ice sheet and CO2 greenhouse effect: a threat of disaster

If the global consumption of fossil fuels continues to grow at its present rate, atmospheric CO2 content will double in about 50 years. Climatic models suggest that the resultant greenhouse-warming

Predicting future atmospheric carbon dioxide levels.

Results from different models for the natural carbon dioxide cycle are compared and special emphasis is given to the type of ocean modeling, behavior of the biosphere, and value of the oceanic buffer factor against carbon dixoide uptake.

Sensitivity of a global climate model to an increase of CO2 concentration in the atmosphere

This study investigates the response of a global model of the climate to the quadrupling of the CO2 concentration in the atmosphere. The model consists of (1) a general circulation model of the

Anthropogenic Albedo Changes and the Earth's Climate

The results suggest that humans have made substantial contributions to global climate changes during the past several millennia, and perhaps over the past million years; further such changes are now under way.
